RAILROAD-BUFFER.

.To all whom it may concern:

Be it known that I, F RANZ RAwIE, a citizen of the German Empire, and resident of Osnabriick-Schinkel, Germany, have invented certain new and useful Improvements in and Relating to Railroad-Buffers, of which the following is a specification.

My invention relates to a railroad-buffer which is adapted to make a sliding movement with relation to the track under the impact of a train and consists in a novel form of such railroad-buffer which is simple in construction and especially adapted for use in connection with easy rolling-stock.

An embodiment of the new slidable railroad-bufier is illustrated on the accompanying drawing in Figure 1 in side elevation and in Fig. 2 in front elevation, partly in section on the line A looking in the direction of the arrow, with the lower portion of the road bed removed.

The numeral a designates a cross-bar carrying the buffer heads. The cross-bar a is mounted on two lateral triangular braces having bracing members Z) provided with spur like extensions penetrating into the bedding of the track. The bracing members I) are connected by plates 0 arranged parallel to the rails e. The lateral plates 0 are shown as being provided with spurs b likewise penetrating into the bedding. The two plates 0 adjacent to the two rails of the track are connected with each other by cross-bars (Z (Z contacting with the under and with the upper side of the railroad-track respectively. The cross-bar (Z is shown in dotted lines in Fig. 1 and Fig. 2 and is arranged at the back end of the bufl'er that is to say at those ends of plates 0 directed toward the train running against the buffer in the direction of the large arrow whereas the cross-bar (Z is arranged at the front end of said plates 0. f is a sleeper forming a crossbar in front of the front spurs Z).

The operation of the buffer is as follows: If the rolling-stock runs against the buffer a displacement of same takes place under the impact. The resistance of the bedding against such displacement of the buffer takes up the force of the impact. Crossbars (Z (Z secure proper guiding of the buffer during the displacement. The tendency of cross-bar (Z to rise under the impact and to lift the rails is overcome by the load of the rolling-stock resting on the Specification of Letters Patent.

rails at the back end of the bufier whereas the tendency of cross-bar d to move downward under the impact of the rolling-stock is taken up by the bedding of the rails which prevents the rails from being depressed under the pressure of cross-bar CF.

The spur members I), b of the buffer penetrating into the bedding and other parts connected thereto such as sleeper f are given such dimensions as necessary to allow the bedding to absorb the force of the impact of the rolling-stock during the displacement of the buffer within desired limits.

What I claim is:

1. A slidable railroad-buffer comprising bracing members provided with spur like extensions adapted to penetrate into the bedding, and guiding members connecting with said bracing members for securing proper guiding of the buffer during displacement, the guiding members being arranged one behind the other, in such man-" ner that a guiding member at the front end of the buffer is adapted to contact with the lower side of a rail of the track, and a guiding member at the back end of the buffer is adapted to contact with the upper side of a rail of the track.

2. A railroad-buifer comprising bracing members provided with spur like extensions adapted to penetrate into the bedding of the track, cross-bars provided at the front end and at the back end of the buffer arranged for crossing the track above and below the rails respectively.

3. A railroad-buffer comprising bracing members provided with spur like extensions adapted to penetrate into the bedding, side plates arranged for lateral contact with the rails of a track and connected by cross-bars arranged in diflerent levels at the front and the back end of said plates, a cross-bar at the front end of the buffer arranged for contact with the upper side of the rails and a cross-bar at the back end of the buffer arranged for contact with the under side of the rails.

4. A slidable railroad-buffer comprising angular braces having bracing members provided with spur-like extensions at front and back adapted to penetrate into the bedding, whereby slidable displacement of the buffer relatively to the rails may take place under impact.

5. A railroad-buffer comprising bracing members provided with spur-like exten- In testimony whereof l have signed this slons adapted to penetrate the beddlng, speelfieatwn 1n the presence of two subserlbsmd bufier bemg capable 0ishdeble cbs- 111g wltnesses.
